Ruby Works
Ruby Works is the lobby factory. After your first Rebirth it turns time into stored Ruby, and it also upgrades chest Rubies and Rebirth Emeralds.
Unlock
The button is locked until you have completed Rebirth once. The first successful Rebirth opens it. Later Rebirths do not reset its levels or the Ruby sitting in storage.
Production and storage
Production ticks once per minute. You start at production level 1 and storage level 1. Each minute adds Rubies equal to the production level, then stops if storage is full. A partial minute does not produce anything.
Base storage is the storage level × 10. Ruby Vault Expansion in Research multiplies that by 1 + 10% per research level. A production-level Potential raises only the Rubies added each minute. It does not raise the storage cap.
| Upgrade | Starts at | What one level does | Cost |
|---|---|---|---|
| Production | 1 Ruby per minute | +1 Ruby per minute before Potential | Emerald × 50 × current level |
| Storage | 10 Ruby | +10 base storage | Emerald × 50 × current level |
| Chest Ruby | 1 | Normal chest Ruby equals the level; a Ruby jackpot equals the level × 10, before time and difficulty multipliers | Ruby × 100 × current level |
| Rebirth Emeralds | 0% bonus | +10% Emeralds from each later Rebirth, per level after the first | Ruby × 100 × current level |
Level 1 production costs 50 Emerald to reach level 2. Level 2 costs 100 Emerald, and so on. Storage uses the same Emerald prices. Chest Ruby and Rebirth Emerald upgrades spend Ruby instead: 100, then 200, then 300.
While you are away
Closed time still counts. Each full minute you missed adds one production cycle at the rate you have now, until storage is full. Minutes that would have overflowed are not saved for later. Collecting the stored Ruby puts it in your Ruby total. Production starts filling the vault again from the room you have left.
What else changes the factory
Potential can add a percent to production. Several of those can exist only as one equipped effect of that kind; the percent on the equipped roll is the one that applies. Research storage and this production percent do different jobs, so a full vault is a storage problem, not a production problem.
The Rebirth Emerald upgrade applies when you confirm a later Rebirth. It increases the Emeralds that score converts into. It does not change the score itself.
